How do I use strtok with every single nonalpha character as a delimeter? (C)

Question

So I have a string:

**BOB**123(*&**blah**02938*(*&91820**FOO**

I want to be able to use strtok to deliminate each word

Answer 1

One approach that can make this easier is to first overwrite all non-alpha characters with spaces:

for (char *p = str; *p; p++)
    if (!isalpha(*p)) *p = ' ';

Now you can use strtok(str, " ")
